| Description | The total number of errors which have occurred on
this port. This counter is the summation of the
values of other error counters (for the same
port), namely:
rptrMonitorPortFCSErrors,
rptrMonitorPortAlignmentErrors,
rptrMonitorPortFrameTooLongs,
rptrMonitorPortShortEvents,
rptrMonitorPortLateEvents,
rptrMonitorPortVeryLongEvents,
rptrMonitorPortDataRateMismatches, and
rptrMonitorPortSymbolErrors.
This counter is redundant in the sense that it is
the summation of information already available
through other objects. However, it is included
specifically because the regular retrieval of this
object as a means of tracking the health of a port
provides a considerable optimization of network
management traffic over the otherwise necessary
retrieval of the summed counters.
Note that rptrMonitorPortRunts is not included
in this total; this is because runts usually
indicate collision fragments, a normal network
event.
A discontinuity may occur in the value
when the value of object
rptrMonitorPortLastChange changes. |
